ROLLING STOCK PPP – DOUBLE DECK TRAINS
MAINTENANCE FACILITY SPECIFICATION - ATTACHMENT 7
ATTACHMENT 7 - SIGNAL FUNCTIONAL SPEC V7.DOC
Three (3) Signalling equipment buildings / bungalows are required as shown on the concept
signalling schematic drawings.
The buildings are to be designed and constructed by PPP Co. (using awnings, external
shades, forced airflow or other appropriate construction methods) to ensure the heat control
inside the buildings is:
• Compatible with the requirements of the equipment installed within the buildings
• Maintained at an acceptable temperature for maintenance staff to work within the
building at all times of the year
Notes:
1) The number, size and positioning of these signalling equipment buildings are indicative
only. The exact number required, their size and location will depend on the final system
design.
2) For tendering purposes it should be assumed that the size of the buildings will be 6m by
4m.
10.3.4.2 Location Cases
Double skinned stainless steel location cases, with flow through ventilation, are to be
provided by PPP Co. as required by the final design. The cases are to be designed and
installed to ensure the heat control inside the cases is compatible with the requirements of
the equipment installed within the cases, and to maintain internal temperatures at ambient.
Note: The number and positioning of these location cases, as shown on the concept
signalling schematic, are indicative only. The exact number required and their location will
depend on the final design.
10.3.5 SIGNALLING POWER SUPPLY
The Signalling power supply will be provided by PPP Co. from one central point and
reticulated throughout the Yard area
The following power supply arrangements are required at the central power supply location
• Dual supplies – “Normal” and “Standby” with automatic changeover facilities.
• Power distribution (signalling mains) between signalling locations can be at Voltages up
to 415V AC. The signalling distribution mains must be transformed down to a nominal
120 volts (at the signal equipment locations) for operating the signalling equipment.
• Changeover from the Normal supply to the Standby supply and back again must not
cause any disruption to the signalling system. Line conditioners and UPS systems are
